Added the possibility to have different boundary conditions per species.

A boundary condition for each species must be indicated in the case
file.
This opens the door to use boundary conditions with different parameters
(for example, a wall temperature, coefficients for reflection or
 absorption...)

The examples included with the code have been updated accordently.
